The maths behind it
This tool uses cost of one return = outbound shipping already spent + return label + handling + the fee you do not get back + the stock value you cannot recover. The break-even return rate is gross profit per order ÷ (gross profit per order + that cost), because a returned order both costs money and never earns its margin. Every intermediate value is shown on screen, so the result can be checked by hand.
The number that moves the total most is not postage but the share of returned stock you can sell again at full price. Dropping that from 80% to 50% typically costs more than doubling the return postage, which is why inspection and repackaging is worth staffing properly rather than treating as overhead.
Where this tool stops
Customer service time, refund processing, the working capital tied up between refund and resale, and the goodwill effect of a good or bad returns experience are all real and none of them are here. Percentages that add to more than 100 are treated as written off.
Frequently asked questions
What does a single return actually cost?
Far more than the return label. The outbound parcel is already paid for and cannot be recovered, someone has to open and check the item, the marketplace usually keeps part of its fee, and a proportion of stock comes back unsellable at full price. Together those routinely reach a quarter to a half of the order value.
Should I charge for returns?
Charging shifts a few pounds of postage but does not touch the larger costs, and it measurably reduces first purchases. The bigger lever is preventing the return: accurate sizing, more photographs, honest descriptions and fit guidance all cut the rate at the point where the cost has not yet been incurred.
Is there a limit on how often I can use the Return Cost Calculator?
Free, unlimited, and no email address required. You can use it a hundred times a day and nothing changes.
Is the Return Cost Calculator safe to use with private information?
No. The Return Cost Calculator runs entirely in your browser using JavaScript. Your input never reaches inputtesthub.com or any third party — open your browser's Network tab while you use it and you will see no request go out.
How is the result calculated?
It uses cost of one return = outbound shipping already spent + return label + handling + the fee you do not get back + the stock value you cannot recover. The break-even return rate is gross profit per order ÷ (gross profit per order + that cost), because a returned order both costs money and never earns its margin. The full working is printed under the result, so you can follow every step rather than trusting a black box.
What do people use the Return Cost Calculator for most?
The jobs it is built for: costing a free-returns policy before offering it. Deciding whether a high-return category is worth keeping. Showing why better sizing information pays for itself. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
What are the limits of the Return Cost Calculator?
Customer service time, refund processing, the working capital tied up between refund and resale, and the goodwill effect of a good or bad returns experience are all real and none of them are here. Percentages that add to more than 100 are treated as written off. Knowing where a tool stops being trustworthy matters more than the cases where it works.
What are the reference figures here?
Outbound shipping is Spent and unrecoverable. Apparel return rates is Commonly 20–40% online. Biggest variable is How much comes back sellable. These are printed on the page itself, so you do not have to take them on trust.
Is the number rounded?
The calculation runs in double precision and the result is shown to ten significant figures, so converting a value and converting it back returns the original. What is displayed is rounded for readability; what is copied is not.
